…的条目类型未在样式文件中定义

Question

我正在使用 overleaf，出现以下警告：

entry type for "hadoop" isn't style-file defined


entry type for "spark" isn't style-file defined

以下是他们的引文：

@software{hadoop,
  author = {{Apache Software Foundation}},
  title = {Hadoop},
  url = {https://hadoop.apache.org},
  version = {0.20.2},
  date = {2010-02-19},
}

@software{spark,
 title={Apache spark™ - unified engine for large-scale data analytics},
 url={http://spark.incubator.apache.org/},
}

我不确定我是否对它们进行了很好的定义？
